I don't want to hijack this thread but I have a very similar problem with recently adding a secure router in front of my Netgear router
Everything else works perfectly (my original router is now in AP mode).
I have two 6555's and neither work now. I know exactly what the problem is and it's similar to the original posters issue, he must have the static IP setting like I did.
And of course the subnet has changed, and my new network cannot see the static ips on the old 192.168.1.* subnet.
I know how to configure my PC via a manual setting of the adapters TCPIP4 connection properties to get my PC talking to the logger via their 192.168.1.* sub net addresses and I get to the Weatherlink config page just fine.
The problem is when I change it back to DCHP and try the IP setting save and/or the configuration save (tried saving both ways in different order) the stupid current 192.168.1.* address keeps repopulating the page, I simply cannot get it to save with the DCHP option, it reverts to the fixed IP setting every time. I cleared out every field in the Static IP settings but the still come back.
I am stumped as to why I cannot seem to save it set back to the DHCP setting.
I even tried reverting to the old router setup and accessing them both while on the good subnet and they still would not save with DHCP set, it does the same thing, keeps rechecking the static ip setting and repopulating the current 192.168.1.* addresses, wth!
I would appreciate any suggestions, I even cleared browser cache to ensure somehow that was not the cause.
